Green Peas, compact star-forming galaxies at zvirgul0.2 have become the best locallaboratories for high-redshift galaxies. While relatively large amounts ofoptical data are available for Green Peas, their X-ray properties remain largelyunknown. We have recently requested XMM-Newton observations of three Green Peasto remedy this situation. We have discovered an intriguingly large X-rayemission in two of the targets, while the third observation was damaged withhigh background. We request here a re-observation of the third target which willallow us to complete the project goals and verify the X-ray luminositydependence on star-formation rate and other galaxy parameters.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
